Flags of the U.S. states and territories

The flags of the U.S. states, territories, and the District of Columbia (Washington, D.C.) exhibit a variety of regional influences and local histories, as well as different styles and design principles.

Recent legislations in Massachusetts (2021) and Illinois (2024) have started the process of redesigning their state flag.

[2][3] Despite a variety of designs, the majority of the states' flags share the same design pattern consisting of the state seal superimposed on a monochrome background, commonly a shade of blue, which remains a source of criticism from vexillologists.

According to a 2001 survey by the North American Vexillological Association, New Mexico has the best-designed flag of any U.S. state, U.S. territory, or Canadian province, while Georgia's state flag was rated the worst (the latter of which has been changed since the survey was conducted).

Many Native American nations have tribal sovereignty, with jurisdiction over their members and reserved land.
